AMSAT-NA to Assume Control of FalconSat-3 Soon
US Air Force Academy satellite was launched in 2007 on Atlas 5 to
560 km, 35.4 degrees orbit, and now is at 468-481km orbit, which is
several years before decay.
The Satellite operates as an amateur V/u store and forward Pacsat at
9k6 (or faster) and will sustain 1w operation.
The AMSAT command team is preparing to assume control once the
final agreements are completed. FalconSat-3 is in a low inclination orbit
presenting opportunities for equatorial and tropical stations.
More details soon.

QB50 ISS CubeSat Deployments May 23-25
The second phase of QB50 CubeSats should be deployed from the
International Space Station over three days from May 23-25, 2017.
Built by university students and research organisations from 23 c
ountries around the world, the QB50 constellation aims to study the
lower thermosphere 200-380 km above the Earth.
11 QB50 CubeSats were deployed in the first phase and a further 17
will be deployed in the second phase. The beacons should be
activated about 30 minutes after deployment.
The QB50 CubeSats have downlinks between 435.7 and 438 MHz and
reports from radio amateurs are most welcome. Beacon data received
can be uploaded to a dedicated QB50 webpage at
https://upload.qb50.eu/
LilacSat-2 (ON02CN), which deploys at 0815 GMT on Tuesday, May 23,
is carrying a FM to Codec2-BPSK Digital Voice transponder, an APRS
digipeater and camera. Further information at
https://amsat-uk.org/2017/05/19/lilacsat-1-cubesat-iss/
Two of the ISS QB50 CubeSats deployed in the first phase, ON01FR
437.020 MHz and ON05FR 436.880 MHz, carry V/U FM transponders.
The uplink frequency for both is 145.860 MHz with 210.7 Hz CTCSS, see

Hi Patrick!
My observations are from a non standard source for comparison purposes. I
have sort of a unique situation.
At work we have a 200" tower. At the top of it there is a VHF/UHF repeater
antenna that was used for our commercial 450 repeater. I connected an iCom
706 to it through some 250 ft of coax. This is by no means made for
satellite work, it's just for me to play with. In comparison to a my HT with
an Arrow it is basically deaf. There is no preamp, nor is the antenna
matched for 2 meters. There is also a boat load of attenuation down 250 ft
of coax. I mainly use it for talking to local repeaters and some simplex work.
With the old radio setup on the ISS I could easily copy it the moment it
crested the horizon. It was full scale by 10 deg high. Since they installed
the new radio setup I can barely hear it on a direct overhead pass.
I have no problem picking it up at home, however my home satellite station
has dual high gain yagis, filtered preamps at the antenna all being driven
with a rotor, short coax and feeding an iCom 910.

Until this morning, I'd probably have to disagree with
you on the performance of the ISS digipeater on 145.825
MHz. I think it had been working about as well as it
was before the old VHF radio failed in mid-October. Since
the replacement VHF radio was installed last month, my
issues have been with how stations were clogging the
frequency with mindless beacons - which seems to have
changed over to having more stations trying to work each
other. A good thing. :-)
For me, the only real change for the ISS packet environment
since the replacement VHF radio was installed would be the
deployment of the CubeSats earlier today. I don't know if
those, somehow, are making the VHF radio deaf. It is eerie
to see that the last packet retransmitted by the ISS
digipeater as of now on ariss.net (just before 2000 UTC)
was from my TH-D74 HT several hours ago.
73!

Michael,
That's an interesting observation. Were you referring to how the
signals sounded last year before that VHF radio failed, or are you
going further back when packet was done with a TM-D700?
I have worked ISS passes the past two evenings from locations near
Dayton. Using my TH-D74 HT and Elk log periodic, the signals I
hear now are the same as I was hearing before the mid-October
failure of the previous VHF radio. I didn't do much packet
through the ISS when that Kenwood radio was being used, so I can't
really speak to how it was a few years back. I hope to be on
again tonight from .... (location yet to be determined, but not in
the Dayton area), even though the passes will be late in the evening,
before flying home tomorrow night.
73!

I regret to inform the Amateur Satellite Community: Bob Vislay, KO6TZ,
died yesterday, 20 May 2017, from a heart attack.
Those of you who are active on the birds know Bob. To me, I have also lost
a long time friend.
May he R.I.P.
